This invention relates to lamp guards, and more particularly guards of a separable character for facilitating'lamp replacement; and it is among the objects of the invention to provide a guard which is strong and durable, and yet readily separable. A further object is the provision of a construction which can be used about switch boards and exposed conductors without danger of short lo circuiting. A still further object is the provision of a closed off guard suitable for situations where extra precautions are desirable.

Other objects and advantages will appear as the description proceeds. To the accomplishment of the foregoing and related ends, the invention, then, consists of the features hereinafter fully described, and particularly pointed out in the claims, the following description and the annexed drawings setting forth in detail certain structure embodying the invention, such being illus trative however of but a few of the various ways in which the principle of the invention may be employed.

In said annexed drawings Fig. 1 is a side elevation of an embodiment of the invention; Fig. 2 is a longitudinal sectional view taken approximately at right angles to Fig. 1; Fig. 8 is a longitudinal central section of a modification; F igwl is a side elevational View of another modification; Fig. 5 is a longitudinal sectional detail of the same; and Fig. 6 is a side elevation, partly in section, of another modification.

Referring more particularly to the drawings, there is shown in Figs. 1 and 2 a guard of fenestrated character, made .up of separable'sections having longitudinal ribs 2 and. cross ribs 3, 4, and being open or unobstructed between such ribs, except at such portion where for instance a reflecting surface may be desired, as at 5. At one end, the sections are provided with mating lugs 6, such as to allow fastening together by screws or the like 7. At the other end, the sections have lapping, projections or mating perforated lugs 8, 9. Desirably, these mating projections are further cut back at the mating face, as at 10. As assembled together in mating relation, a suspension member may be ap- 1929, Serial No. 364,132.

plied in a manner to also hold the sections together, for instance a book 11 having a pin or collar 12 may thus be seated in the opening, aligning the sections and being held against axial displacement by the collar 12, while permitting s'wivelling movement. With the sections so assembledand clamped about a lamp socket by means of the takeup screws 7, a lamp therewithin is adequately surrounded by a framing of well braced arrangement, and if the sectionsbe covered with insulative material if basically of metal, any danger of short circuiting in the usage of the deviceabout exposed conductors, bus-bars or contacts is avoided. The sections may also bemade entirely of insulative' materiahby .molding, pressing" or otherwise suitably forming, rubber, composition, bakelite, etc., being thus applicable.

In the use of some lights in'which' the filament instead of being arranged longitudinally of the bulb, is placedas a crown or part circle transversely of the bulb, special provision for outlet of the light endwise of the bulb is desirable, and for this, the separation of the sections or shell members of the guardmay be arranged on a transverse plane or at the end of the bulb, as for instance in Fig. 3. In such construction the lower section or shell member 13 may be provided with a tightening clamp portion 14 having screw takeup 15 through appropriate lugs, whereby to permit clamping onto a lamp socket, and the other section may take the form of a disk 16 having fenestrations or openings, and being attach-- able to the section 13 in suitable manner, as by screws, bayonet joint, or more usually screw thread connections 17. A'suspension member, as for instance a hook 11, may be carried in the side ofthe member 13 (Fig. 3), or if preferred, at the end (Fig. 4:) in a suitable cross rib or the like.

Where it is desired to further reduce hazards such for example as from splashing water, gasoline vapors, etc., by more com 'pletely enclosing the lamp, glass closures 18 may additionally be incorporated Within the interior, being positioned against one or both sections or shell members, and a gasket may be further applied inorder to make a tight j vapor-proof guard. On this same general basis a laterally opening guard may also be had, as for instance in Fig. 6, a lateral cover or shell member 16 being detachably connected in any suitable manner, as by screws, bayonet joint, or screw-threaded engagement, and the remainder of the guard may be in one or two sections or shell members, preferably two, F or instance, the section 5 may be in the form of a half shell, and the anterior section 19 to receive the cover 16 may be joined by suitable means, as screws 20 and clamp 7'. A suspension member, as a hook 11 may again be provided, a suitable con nection, for instance a cotter pin retaining means 21 allowing of suiiicient convenient relative movement. A closure of glass or other transparent material 18 may be further supplied if desired.

lVhile the casing members may be made of metal, it is generally preferable to employ insulative material, or at least an insulative covering over metal. By employment of insulative material, the sections may be molded or pressed or otherwise suitably shaped, and thus afford complete insulative protection Without danger of chipping off or peeling.

Other modes of applying the principle of the invention may be employed, change being made as regards the details disclosed, provided the means stated in any of the following claims, or the equivalent of such, be employed.

I therefore particularly point out and dis tinctly claim as my invention:

1. A portable lamp guard, comprising separable shell members including lateral fenestrations, means at one end for clamping the guard onto a lamp socket, one of said separable shell members being of disc-form located at a position removed from the end receiving the lamp socket, and screw-threaded means for holding said separable shell members together.

2. A portable lamp guard, comprising separable shell members including lateral tenestrations, means at one end including mating lugs and take-up screws for clamping the guard onto a lamp socket, one of said separable shell members being of disc-form, and screw-threaded means for holding the same to its adjacent shell member.

3. A portable lamp guard, comprising separable shell members including lateral fenestrations, means at one end including mating lugs and take-up screws for clamping tne guard onto a lamp socket, one of said separable shell members being of disc-form, screw-threaded means for holding such member to its adjacent shell member, and a sealing glass held by such disc member to said other shell member.
